## Project Laboratory on Distribution Grid Simulation

Module Number: EI80008

Duration: 1 Semester

Recurrence: Summer Semester

Language: English

Number of ECTS: 5

## Staff

Professor in charge: Rolf Witzmann

## Amount of work

Class attendance: 45

Private study: 105

Total:150

## Description of achievement and assessment methods

Students must hand in a written report for each of the 5 case studies conducted by the group. One final presentationmust be given by the group. In the exam it should be demonstrated that the crucial points of the task have beenunderstood and different aspects have been considered for the final solution. The final grade is an averaged grade from the written reports (75%) and from the final presentation (25%).

## (Recommended) requirements

extensive knowledge on power transmission (recommended) e.g. Power Transmission Systems (EI8032)

## Contents

- grid modelling based on geographical information

- load flow calculation in order to validate the grid model

- identification of necessary grid extensions in low

-voltage grids

- load profile calculations for the computation of grid losses

- calculation of imbalances in low-voltage grids

- calculation of harmonic distortions in low-voltage grids

- dimensioning of network protection for simple configurations

## Study goals

Upon completion of the module, students are able to deal with typical questions regarding the simulation of electricalpower distribution grids. The students are able to model an electrical grid with its electrical components, perform load flow calculations, assessthe results and develop appropriate grid extensions. Furthermore the students are capable of conducting and interpreting time series simulations. The students are also able to implement unbalances and harmonic distortions in the grid, as well as deriving possiblemeasures to face these problems. They can implement a network protection concept for simple network configurations.

## Teaching and learning methods

The tasks are to be solved autonomously in computational aided simulation. The students will be provided with thetheoretical background in digital form.

## Media formats

The tasks are to be solved with one of the most common commercial load flow calculation programs. This programmis provided for the duration of the course.
